HINGE Filed June 15, 1931 Patented July l1, 1933 UNrrEn STATES PATENT oFF-Ice EDWIN W. NORTH, OF BCKFGRD, LLNOES, ASSTLG'NOB/ T0 NATIONAL LOCK CO.,KOF EOCKFORCD, ILLINOIS, A CORPORATION F DELAWARE Hman .application flied June 15,

This invention pertains to hinges and more particularly `to a concealed pintle hinge especially suited for light service such as cabinet use although it will be manifest that v the principles involved may be utilized to advantage upon heavy hinges.

It is the purpose of this invention to provide a hinge embodying a concealed pintle enclosed in such a manner that the hinge may be constructed economically both from the point of view of the amount and kind of material used and the steps involved in the fabrication of the material into a hinge.

Heretofore concealing the pintle of a hinge has involved relatively expensive construction, that is, the manufacture thereof was costly not only from the point of material being used but from the shaping and forming of the material into a concealed pintle hinge. In accordance with this invention it is not only possible but practical to manufacture, commercially in large quantities, concealed pintle hinges by stamping or pressing the wings of the hinge from sheet metal. ln the preferred form the base or stationary wing is Aprovided with a pair of opposed hollow pintle supporting pockets and is also provided with integral locking members which retain the pintle within the supporting pocket.

A better understanding of this invention `will be had from given in connection with which:

Fig. 1 is a section taken in a horizontal plane along line 1-1 of Fig. 2.

i' Fig. 2. is al front elevation of a hinge em bodying the features of this invention.

Fig. 3 is a rear elevation of the same.

Fig. 4 is a section on line L -l of Fig. 2.

40- Fig. 5 is av partial section taken on line 5-5 of Fig. 2.

As can be seen from the drawing in the illustrated embodiment of this invention, a hinge is shown that is particularly suitable for cabinet doors and comprises a relatively stationary or base wing l to which is pivotally connected a moving wing 2 by means of a pintle 3.

The stationary wing the drawing, in

is a relatively long .501 narrow plate of sheet metal having a pair of the following description 1931.' semi no. 544,334.

opposed spaced pintle pockets fl str ck outwardly from one face thereof. These vpockets being struck` out vfrom the sheet metal wing" arev hollow and provide spaced recesses 6 up" on their under side and closed at one end for receiving and concealing the ends of the pintle. The pintle may be knurled at one .or both ends if desired. The base Wing is also provided at one edge adjacent the two pintle pockets with a pair of tongues 7 one adjacent 559 each pocket which may be curled around the ends of the pintle to retain the same within the recesses. Y

The moving wing 2 is provided at one edge with a tongue 8 of reduced width equal to 35 the distance between the pintle pockets which may be curled about the intermediate portion of the pintle. The shoulders 9 formed by forming the reduced tongue 8 strike the edge 10 and limit the movement of the wings in one direction.

From the foregoing description it will be observed that a concealed pintle bingev has been provided which may be readily manufactured from sheet stock, and in which the 7 pintle is entirely enclosed and secured in position by a pair of tongues formed integrally with the base wing by curling them about the pintle after the wings have been assembled, to effectively lock the wings pivotally to- SQ gether. The hinge may be cheaply manufac- Y tured since it involves only stamping of sheet stock. The construction provides a very neat and very rugged hinge due to the pintle being securely supported at both ends and the en- 375, tire intermediate portion of the movable wing providing a long bearing for the latter wing.

lt will be obvious that minor changes may be made in the details of construction and that the hinge may be constructed of material K other than sheet stock without departing from the spirit and scope of the invention as defined in the appended claims.

I claim:

1. A hinge comprising a pair of wings and 9F a pintle pivotally securing Vsaid wings together, ene vof said wings having a pair of spaced pockets arranged to receive the ends of said pintle and a pair of integral tongues projecting from said wing andv curled in- Wardly around the ends of said pintle to secure the same Within the pockets.

2. In a hinge: a hinge member having a pintle Whose end portions extend outwardly from its opposite sides; a second hingeA member made of sheet metal having spaced hollow'extensions embracing the first-mentioned hinge member and covering the pintles end portions, said extensions having tongues bent under said end portions respectively to connect the hinge members together turnably.

3. In a hinge: a hinge member having a pintle Whose end portions extend outwardly from its opposite sides; a second hinge member made of sheet metal having spaced hol- 10W conical extensions embracing the firstmentioned hinge member and covering the pintles end portions, said extensions having tongues bent under said end portions respectively to connect the hinge members together turnably.

t. A hinge comprising a pair of Wings, a

pintlev pivotally securing said Wings to-` nature.
